Product Overview
This series of gasoline generators features a unique butterfly-style frame – robust, stable, and easy to transport. Available in 2000W, 2500W, 2800W, 3000W rated output, each unit is tailored to customer needs. Choose between recoil (pull-start) or electric start (push-button). Motor winding can be high-efficiency pure copper or cost-effective aluminum. Powered by single-cylinder, 4-stroke engines (163cc–223cc, 5.5HP–7.5HP) with a 15L fuel tank for long runtime. Ideal for home backup, outdoor work, small construction, shops, and events.

FAQ
Q1: Are 2000W and 3000W models the same size?
A: Similar but slightly different. 2000W/2500W: approx. 605×430×435mm; 3000W: 620×450×445mm. All butterfly frames support stacking.
Q2: How to choose between pure copper and aluminum winding?
A: If you use the generator >10 hours/week or for sensitive equipment (fridge, pump, electronics), choose copper. For occasional emergency backup only, aluminum is fine. Both deliver stable voltage.
Q3: Can it run on natural gas or LPG?
A: Standard is gasoline. Dual-fuel carburetor is available on request (contact us for custom order).
Q4: What is needed for electric start?
A: Electric start kit (starter motor + relay) + 12V battery (7Ah recommended). We can supply the battery or you can buy locally.
Q5: Can I get both 220V and 380V from one generator?
A: Some models (e.g., HH3900-DV) support single-phase 220V and three-phase 380V switchable output. Please specify your voltage requirement when ordering.
Q6: What is the warranty?
A: 1-year whole machine warranty (2 years for copper motor). Consumables (spark plug, air filter) not included.

Pain Point Solutions
Customer Pain Point Our Solution
Wrong power – either too weak or wasteful 2000/2500/2800/3000W precisely selectable – match your real load
Hard to pull-start, especially in winter or for elderly users Optional electric start – push button and go
Copper motor too expensive, aluminum might not last Clear pricing for both; extended warranty for copper option
Weak frame, easily scratched or bent during transport Butterfly frame with anti-impact corners, stackable design
Noise complaints from neighbors Optimized muffler & vibration pads – only 95dB@7m
